DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-3, a shelving unit in accordance with the preferred embodiment of the present invention comprises a backplane including an upright support 2, a transverse connecting rack 1 detachably combined with the upright support 2, a first connecting bracket 21 secured on the upright support 2, a second connecting bracket 11 secured on the connecting rack 1 and detachably combined with the first connecting bracket 21, and a fastening pin 22 extending through the first connecting bracket 21 and the second connecting bracket 11 to combine the first connecting bracket 21 and the second connecting bracket 11 together.

The first connecting bracket 21 of the backplane has a side provided with a hollow mounting seat 210. The mounting seat 210 of the first connecting bracket 21 has an inner portion provided with a receiving space 211. The mounting seat 210 of the first connecting bracket 21 is provided with two opposite protruding ears 212, and the receiving space 211 of the mounting seat 210 is located between the two protruding ears 212 of the mounting seat 210. Each of the two protruding ears 212 of the mounting seat 210 is provided with a first through hole 213.

The second connecting bracket 11 of the backplane has a side provided with a mounting post 111 combined with the mounting seat 210 of the first connecting bracket 21 by the fastening pin 22. The mounting post 111 of the second connecting bracket 11 is inserted into the receiving space 211 of the mounting seat 210 and is clamped between the two protruding ears 212 of the mounting seat 210. The mounting post 111 of the second connecting bracket 11 is provided with a second through hole 112.

The fastening pin 22 extends through the first through hole 213 of each of the two protruding ears 212 of the mounting seat 210 and the second through hole 112 of the mounting post 111 to combine the mounting seat 210 of the first connecting bracket 21 and the mounting post 111 of the second connecting bracket 11 together.

In assembly, the mounting post 111 of the second connecting bracket 11 is inserted into the receiving space 211 of the mounting seat 210 and is clamped between the two protruding ears 212 of the mounting seat 210. Then, the fastening pin 22 extends through the first through hole 213 of each of the two protruding ears 212 of the mounting seat 210 and the second through hole 112 of the mounting post 111 to combine the mounting seat 210 of the first connecting bracket 21 and the mounting post 111 of the second connecting bracket 11 together and to combine the first connecting bracket 21 and the second connecting bracket 11 together so as to mount the connecting rack 1 onto the upright support 2.

On the contrary, after the fastening pin 22 is removed from the first through hole 213 of each of the two protruding ears 212 of the mounting seat 210 and the second through hole 112 of the mounting post 111, the mounting post 111 of the second connecting bracket 11 can be detached from the receiving space 211 of the mounting seat 210 so as to detach the connecting rack 1 from the upright support 2.

Accordingly, the first connecting bracket 21 and the second connecting bracket 11 are combined together and detached from each other by the fastening pin 22, so that the upright support 2 and the connecting rack 1 are assembled and disassembled easily and quickly, thereby facilitating a user assembling and disassembling the backplane of the shelving unit. In addition, the backplane of the shelving unit has a simplified construction, thereby decreasing the costs of fabrication and inconvenient to customers.

Referring to FIGS. 4-6 with reference to FIG. 2, the shelving unit further comprises a support frame 3, and the upright support 2 of the backplane is detachably mounted on the support frame 3.

The support frame 3 is provided with at least one locking hole 32. The locking hole 32 of the support frame 3 has an upper end provided with a circular passage 320 and a lower end provided with an elongate locking slot 322 having a dimension smaller than that of the circular passage 320. The support frame 3 is further provided with a positioning hole 31. The positioning hole 31 of the support frame 3 is located above the locking hole 32 of the support frame 3.

The upright support 2 of the backplane is provided with at least one locking knob 24 detachably locked in the locking hole 32 of the support frame 3. The locking knob 24 of the upright support 2 has a first end provided with a guide post 240 protruding outwardly from the upright support 2 and a second end provided with a circular locking piece 242 inserted through the circular passage 320 of the locking hole 32 and locked onto the locking slot 322 of the locking hole 32. The guide post 240 of the locking knob 24 is inserted through the circular passage 320 of the locking hole 32 and is detachably locked in the locking slot 322 of the locking hole 32. The locking piece 242 of the locking knob 24 has a dimension equal to that of the circular passage 320 of the locking hole 32 and greater than that of the locking slot 322 of the locking hole 32.

The upright support 2 of the backplane is further provided with a positioning plug 23 detachably positioned in the positioning hole 31 of the support frame 3. The positioning plug 23 of the upright support 2 is located above the locking knob 24 of the upright support 2 and is directed downward toward the positioning hole 31 of the support frame 3. The positioning plug 23 of the upright support 2 is attached to the upright support 2 by a fixing strut 230. The positioning plug 23 of the upright support 2 is positioned in the positioning hole 31 of the support frame 3 when the locking knob 24 of the upright support 2 is locked in the locking hole 32 of the support frame 3 and is detached from the positioning hole 31 of the support frame 3 when the locking knob 24 of the upright support 2 is unlocked from the locking hole 32 of the support frame 3.

In assembly, when the upright support 2 of the backplane is mounted on the support frame 3, the locking piece 242 of the locking knob 24 extends through and protrudes outwardly from the circular passage 320 of the locking hole 32. Then, the upright support 2 of the backplane is moved downward relative to the support frame 3 by the gravity of the backplane so that the guide post 240 of the locking knob 24 is inserted into and locked in the locking slot 322 of the locking hole 32, and the locking piece 242 of the locking knob 24 is locked onto the locking slot 322 of the locking hole 32. At the same time, the positioning plug 23 of the upright support 2 is moved downward and positioned in the positioning hole 31 of the support frame 3 when the locking piece 242 of the locking knob 24 is locked onto the locking slot 322 of the locking hole 32.

Referring to FIG. 7 with reference to FIGS. 4-6, the support frame 3 is further provided with at least one screw bore 33. The screw bore 33 of the support frame 3 is located above the locking hole 32 of the support frame 3. The upright support 2 of the backplane is further provided with at least one fixing bore 25. The fixing bore 25 of the upright support 2 is located above the locking knob 24 of the upright support 2. The shelving unit further comprises at least one fastening bolt 4 extending through the fixing bore 25 of the upright support 2 and screwed into the screw bore 33 of the support frame 3 to combine the upright support 2 and the support frame 3 together.
